NERVES

How to stop your voice from shaking when you present

You know the material. Then you stand up, start the first sentence, and feel the wobble low in your throat.

It feels like the whole room can hear it. They may notice less than you think (more on that below). The bigger cost is what the shake does to you. Once you notice it, you start managing your voice instead of making your point, and that's when a talk slips away from you.

Why your voice shakes

Standing up to speak sets off the same stress response as any other threat. Adrenaline rises and your heart speeds up. The muscles in your chest, neck and throat tighten. Your breathing turns quick and shallow, high up near your collarbones.

Your voice is air moving past your vocal folds. A tight chest and short, uneven breaths can make it wobble, and steadier breathing often helps it settle.

So when nerves are the cause, breathing is a good place to start. You can practice it ahead of time.

The audience hears less than you do

In a 2003 study, the psychologists Kenneth Savitsky and Thomas Gilovich asked people to give short speeches and then rate how nervous they had looked. The speakers thought their nerves showed more than the people watching did. Speakers who were told about this gap before they started rated their own speeches higher, and observers saw them as more composed (Journal of Experimental Social Psychology).

Consider yourself told. What feels obvious from the inside may be much less obvious to the people listening.

Three drills for the morning of your talk

Do these out loud on the morning of the talk, and again 15 minutes before you go on. The set takes about five minutes.

1. Breathe out longer than you breathe in

Breathe in through your nose for a count of four, then out through your mouth for a count of six. Do five rounds. Keep your shoulders down so the breath goes into your belly. A slow exhale may help you settle.

2. Lip trills

Close your lips loosely and blow air through them so they flutter, like a kid making a motorboat sound. Add your voice and slide slowly up and down your range. A trill only keeps going on a steady stream of air, so it's a gentle way to practice steady airflow. Try it for a minute or two. If trills feel silly in an office, hum the same slides with your mouth closed.

3. Count on one breath

Take a normal breath and count out loud from one to ten on a single exhale, at your presenting pace. Then try one to fifteen. Stop when the air runs out instead of squeezing out the last numbers.

Listen for the point where your voice starts to thin. That's about as much as you can say on one breath, and long sentences are where a shaky voice gives out first. On the day, keep your sentences inside that length and breathe between them. The one-breath rule in how to talk slower works the same way.

In the minute before you speak

Breathe all the way out before your first word, then let the next breath drop in low. Nervous speakers tend to gasp in high instead.
Plant both feet and let your shoulders drop.
Know your first two sentences word for word. The shake is usually worst at the start and eases once you're moving, so take the guesswork out of the opening.
Start slower than feels natural. A calm first sentence gives your breathing a pattern to follow.

If it shakes anyway

Keep going. Finish the sentence, breathe out, and take the next one a little slower. A pause after a point looks deliberate, and it gives your breath time to settle. If your mouth is dry, take a sip of water while a slide changes.

Skip the apology. A wobble the room barely noticed becomes the topic once you point it out.

Over the long run, say it out loud often

Nerves tend to run highest when a situation feels new, and every out-loud run-through makes the talk a little less new. Going over it silently in your head doesn't train your voice or your breath. Say it out loud, record it and listen back. Several short run-throughs across a week tend to do more than one long rehearsal the night before. How to record yourself practicing a speech walks through the loop.

Practice it in Charisma Lab

The Warm-Up tab has guided drills like these. Breath Reset is a minute of box breathing, and Lip Trills and Humming Scales take 90 seconds each. Quick Boost puts a breath, lip trills and your power statement into one minute, for the hallway before you walk in.

Then rehearse the talk in Speak. Tap the center, tell the coach what the talk is for and say it out loud. You hear each take played back, and then the coach tells you what to change on the next one. In Train, Volume Lock checks whether your volume drops on the last word of a line, which is where a short breath tends to give out.

Setup is free and includes a short live session with the coach. See pricing.

FAQ

Why does my voice shake when I present but not with friends?

With friends nothing feels at stake, so your breathing stays easy. In front of a room the stress response can tighten your chest and shorten your breath, which leaves your voice less air to work with.

Can the audience tell my voice is shaking?

Possibly less than you think. In the study above, speakers overestimated how visible their nerves were. Keeping an even pace after a wobble also gives listeners less to notice.

Does drinking water help?

A dry mouth makes the wobble worse, so sip water before you start and keep a glass nearby. Water won't change your breathing, though, so do the drills too.

When should I get a shaky voice checked?

See a doctor or a speech-language pathologist if your voice also shakes in calm everyday conversation, or if the shake is getting worse over time. Nerves in front of a room are normal. A voice that also shakes at the kitchen table is worth a professional look.
